Department of Neurosurgery Faculty Papers

STUDY DESIGN: Multicenter study.

OBJECTIVES: The COVID-19 pandemic has obligated physicians to recur to additional resources and make drastic changes regarding the standard physician-patient encounter. In the last century, there has been a substantial improvement in technology, which over the years has opened the door to a new form of medical practicing known as telemedicine.

METHODS: Healthcare workers from three hospitals involved in the care for COVID-19 patients in the united states were invited to share their experience using telemedicine to deliver clinical care to their patients.

RESULTS: Since the appearance of this worldwide outbreak, social distancing has been a …

Department of Neurosurgery Faculty Papers

Background. Endosaccular coiling, vessel occlusion, stenting, stent-assisted coiling, and flow diversion are all endovascular treatment options for pseudoaneurysms (PAs) of the head and neck. We explore different clinical situations in which these were selected for PA management at a single institution. Methods. Over a period of ten years, 33 patients presented to our hospital with PAs of the head and neck. Their outcomes and procedural complications are discussed. Results. We observed a complication rate of 18.2% (6 of 33), consisting predominantly of infarcts following vessel occlusion. As measured by the modified Rankin Scale, 25 (75.8%) patients had achieved favorable outcomes …

Introduction. The variables that predispose to postcranioplasty infections are poorly described in the literature. We formulated a multivariate model that predicts the risk of infection in patients undergoing cranioplasty. Method. Retrospective review of all patients who underwent cranioplasty following craniectomy from January, 2000, to December, 2011. Tested predictors were age, sex, diabetic status, hypertensive status, reason for craniectomy, urgency status of craniectomy, location of cranioplasty, reoperation for hematoma, hydrocephalus postcranioplasty, and material type. A multivariate logistic regression analysis was performed. Results. Three hundred forty-eight patients met the study criteria. Infection rate was 26.43% (92/348). Of these cases with infection, 56.52% …

A prospective, multicenter phase I trial was undertaken by the North American Clinical Trials Network (NACTN) to investigate the pharmacokinetics and safety of, as well as obtain pilot data on, the effects of riluzole on neurological outcome in acute spinal cord injury (SCI). Thirty-six patients, with ASIA impairment grades A-C (28 cervical and 8 thoracic) were enrolled at 6 NACTN sites between April 2010 and June 2011. Patients received 50 mg of riluzole PO/NG twice-daily, within 12 h of SCI, for 14 days. Peak and trough plasma concentrations were quantified on days 3 and 14. Peak plasma concentration (Cmax) and …

Introduction

Incidence rates for concussion will continue to grow along with the increasing awareness and improvements in diagnosis. Headache is a hallmark feature of post-concussion syndrome. Post-concussion headache (PCH) is highly prevalent in the military with as high as 97.8% reporting having headaches1. occurring in up to 85% of athletes following 2-4. In the Military and sports, return to duty or play guidelines state that a soldier/player should be asymptomatic before returning to physical activity. However, headache following concussion is commonly dismissed. PCH can be a new headache resulting from head trauma or worsening of pre-existing headache …

Background: There is convincing preclinical evidence that early decompression in the setting of spinal cord injury (SCI) improves neurologic outcomes. However, the effect of early surgical decompression in patients with acute SCI remains uncertain. Our objective was to evaluate the relative effectiveness of early (,24 hours after injury) versus late ($24 hours after injury) decompressive surgery after traumatic cervical SCI.

Methods: We performed a multicenter, international, prospective cohort study (Surgical Timing in Acute Spinal Cord Injury Study: STASCIS) in adults aged 16–80 with cervical SCI. Enrolment occurred between 2002 and 2009 at 6 North American centers. The primary outcome was …

Multiple lines of evidence have validated the Rho pathway as important in controlling the neuronal response to growth inhibitory proteins after central nervous system (CNS) injury. A drug called BA-210 (trademarked as Cethrin(®)) blocks activation of Rho and has shown promise in pre-clinical animal studies in being used to treat spinal cord injury (SCI). This is a report of a Phase I/IIa clinical study designed to test the safety and tolerability of the drug, and the neurological status of patients following the administration of a single dose of BA-210 applied during surgery following acute SCI. Patients with thoracic (T2-T12) or …

Department of Neurosurgery Faculty Papers

BACKGROUND: Opioid agonist drugs produce analgesia. However, long-term exposure to opioid agonists may lead to opioid dependence. The analgesic and addictive properties of opioid agonist drugs are mediated primarily via the mu-opioid receptor (MOR). Opioid agonists appear to alter neuronal morphology in key brain regions implicated in the development of opioid dependence. However, the precise role of the MOR in the development of these neuronal alterations remains elusive. We hypothesize that identifying and characterizing novel MOR interacting proteins (MORIPs) may help to elucidate the underlying mechanisms involved in the development of opioid dependence. RESULTS: GPR177, the mammalian ortholog of Drosophila …


The Efficacy Of Surgical Decompression Before 24 Hours Versus 24 To 72 Hours In Patients With Spinal Cord Injury From T1 To L1--With Specific Consideration On Ethics: A Randomized Controlled Trial., Vafa Rahimi-Movaghar, Soheil Saadat, Alexander R Vaccaro, Seyed Mohammad Ghodsi, Mohammad Samadian, Arya Sheykhmozaffari, Seyed Mohammad Safdari, Bahram Keshmirian Jan 2009

Department of Neurosurgery Faculty Papers

BACKGROUND: There is no clear evidence that early decompression following spinal cord injury (SCI) improves neurologic outcome. Such information must be obtained from randomized controlled trials (RCTs). To date no large scale RCT has been performed evaluating the timing of surgical decompression in the setting of thoracolumbar spinal cord injury. A concern for many is the ethical dilemma that a delay in surgery may adversely effect neurologic recovery although this has never been conclusively proven. The purpose of this study is to compare the efficacy of early (before 24 hours) verse late (24-72 hours) surgical decompression in terms of neurological …

The neurogenetic prototypic disease on which we chose to test our gene therapy strategy is Canavan disease (CD). CD is an autosomal recessive leukodystrophy associated with spongiform degeneration of the brain. At present the disease is uniformly fatal in affected probands. CD is characterized by mutations in the aspartoacylase (ASPA) gene, resulting in loss of enzyme activity. In this review, recent evidence is summarized on the etiology and possible treatments for CD. In particular, we discuss two gene delivery systems representing recent advances in both viral and liposome technology: a novel cationic liposome-polymer-DNA (LPD) complex, DCChol/DOPE-protamine, as well as recombinant …
